Disastrous mistakeBy HD29on 8/6/2017

This stuff is dust--it's so fine it will pass right through a filter sock until there's nothing left. It coated my tank in red and caused an algae explosion.

Bad batch?By Jameson 6/2/2017

I decided to try this after using phosban. This was basically powder compared to phosban. I don't know if I got a bad batch or if that's how it was. Also very hard to clean using the Innovative Marine reactor

Product works greatBy Matton 5/29/2017

I use it in a reactor in the sump with carbon and it is helping to keep nitrates and phosphates very low.

Best I have usedBy Terrenceon 5/21/2017

I really like BRS GFO. I find that it is the best I have used to reducing Phosphates. Good price as well. Worth it.

It works well (enough)By City Reefer on 5/5/2017

I use this in the BSR dual reactor. It works well enough but for me, it gets exhausted too fast. For my size tank (110 gal D.T. about 130 gal total water volume) I have to fill the cartridge almost all the way. That does not give me a lot of room for flow adjustment.

I like the product but I will be getting the BRS High Capacity GFO next time I order.

Run this media thru a the BRS reactor with great results. Keeps my Phosphates in ckeck and last longer than the other brands i have used.

Have had it running for about a month now and has significantly maintained my phosphate at ultra low levels

Great product!By Grant ONon 3/16/2017

I've used several different gfo's, mainly rowaphos. I prefer this product much more for several reasons- it's cheaper, better and much more cleaner. I found with rowaphos I would have to run my reactor with at least a gallon of water before it comes out clear. With this gfo it took probably less than half a gallon! Highly recommended

Still waiting for resultsBy RBTAon 3/9/2017

RBTA wouldn't recommend this product to a friend

So far after 2 weeks of use in a BRS GFO & Carbon Reactor - Deluxe I have seen no reduction in phosphates. After reading all the reviews I am disappointed in the results that my tank is showing. At this time I am not giving this product a good review, I will update at a later date if and when I see some positive results.

Best GFO on the marketBy Mitchon 3/6/2017

I really like the BRS GFO. I find that it is the best value and best GFO that you can buy. I change mine once a month and it makes a big difference in the Phosphate levels. Great for controlling algae and a bargain price.
